DESCRIPTION

Continuous Database Migration Package to databases in sync with the development of the application to keep.

INSTALL

Installation of DBIx::Schema::Changelog is simple:

    perl -MCPAN -e 'install DBIx::Schema::Changelog'

    wget -O - http://cpanmin.us | sudo perl - DBIx::Schema::Changelog

(If you don't have root access, omit the 'sudo', and cpanminus will install DBIx::Schema::Changelog and prereqs into ~/perl5.)

MAIN CHANGELOG

Implemnt Subchangelog files

There are two type of changelog files. The main changelog which must be called changlog and the specific file end

        ...
        changelog.yml
        changelog.json
        ...

The subchangelog files are in the same directory as the main changelog file. The difference is that the sub changelog files are defined by postfix.

In the changelog file:

        changelogs: 
  - "01"
  - "..."

The subchanglog is:

        changelog-01.yml
        changelog-....yml
